Benzodiazepines

Hey ladies me and my husband want to get pregnant now for #2 finally after not being able to for various reasons. Our son is 3.5 and I really don’t want to wait much longer. I have been taking benzodiazepines on and off the last year bc of a very stressful year and was wondering how long I need to be off them before we can start trying? Does anyone have any idea? Of course I will run it by my psychiatrist but until then
